Batboard

Hello all,

I received an old model Micor repeater staion that was supposedly working. Hooked it up, can't seem to get any transmission. I'm going to find a manual and start tracing it out but a couple of things popped out to me.

It came with the following cards. Do I need all of these?

Line Driver
Station Control Module
Time Out Timer
F1 Control Module
Guard Tone Decoder (with a VibraSponder 2175.0 reed)
Squelch Gate
Repeater Control Module

Also, where does one change the PL for such a beast?

Like I said, I'm going to get a manual and try to figure it out, put I was wanting some heads up before it got here.

Many thanks,

don't even start without the book



you need as a minimum the control module and squelch gate cards.

This sounds like you have a Tone Remote Control “Carrier Squelch” Micor Repeater with Repeater Set Up & Knock Down Option.

You will need all of these modules plus a Tone Remote Console to set up the Wire Line controlled repeater at a remote location, either in the building or at some other location. If there was a PL Decoder board it would have been mounted directly to the Audio-Squelch board just to the right of the receiver’s RF-IF board. The receiver RF-IF board has multiple holes on the left hand side and the top hole should have a RX F1 Channel Element mounted to the board. To verify this RX Channel Element, there’s a cover on the rear of the metal chassis with 4 Philips screws holding it in place.

In the upper left hand corner id the Exciter board (with 4 holes on the left hand side) the very top hole is where the TX F1 Channel Element should be mounted and to verify the TX Channel Element is mounted to the Exciter board, loosen up the 2 Philips screws to remove the metal cover on the rear chassis. In the middle of this board is a rectangular hole where the TX Tone PL Vibrasender would be accessible with the TX PL Encoder board and this mounts directly to the Exciter.

If every thing is in place on the transmitter, you’ll need a good reliable RF Wattmeter (Bird 43 or equivalent with the proper sensing slug 100 Watt) and a 100 Watt RF Dummy Load connected to the RF Output Connector, the station powered up and you can Key the station using the very top PTT slide switch on the Station Control Module. There are no visual lights on the Micor to indicate when it is transmitting. The only module that can be removed is the Time Out Timer for your test.
